Pop-Up Form To Mimic Input Box - How do I reference a field on it?

[ChemistZ]

I am creating a pop-up form that will hopefully substitute for an input box on an underlying form. I want the pop-up form to have a text box that a user can type a value in and then I want that value to be placed in a text box on the underlying form. The code will reside in the OnOpen event of theunderlying form but I can't seem to figure out how to reference the text box on the op up form. Can anyone help?

Have you tried assigning the value of the pop-up form text box to a gobal variable (in a module) and that at the on_focus or the on_activate event of the underlaying form assign that variable to the underlaying textbox ??
